SOLIS Data

Synoptic Optical Long-term Investigations of the Sun (SOLIS) is a synoptic facility for solar observations over a long time frame that is funded by the NSF and designed and built by the NSO.

Data is accessed via FTP server or through quicklook plots.

Note: As of October 22, 2017, SOLIS is offline and being relocated to BBSO.Note: The Milne-Eddington inversion of VSM/6302v data between June 17 and October 22, 2017, is currently affected by an unintended calibration issue.

SOLIS VSM 6302V Known Issues

As of June 17, 2017, the Milne-Eddington inversion code applied to VSM/6302v data (as described in NSO Techical Report NSO/NISP-2017-02) was modified (VERSION=6.4) to consider both of the 630.15 and 630.25 nm spectral lines. (Prior to that, in VERSION<6.4, only the 630.25 nm line was used.)

Subsequently, it was discovered than an unintended diagnostic calibration function was inadvertently incorporated at the same time. The affected magnetograms and synoptic maps will be reprocessed accordingly in the near future. However, we are currently re-evaluating the 2-line inversion results in light of this.

Note that the VSM/6302v spectra (e.g., the publicly available spectral cubes) are not affected by this issue.
